I have a Dolby cat 114 power supply which it's output wires are red,green,yellow & blue. I'm wondering are the outputs DC or AC
& what the voltages are. I haven't taken it apart yet,so was it for a processor-which models- or something else?

I just changed out a flaky power supply in our Dolby CP50 processor a few months back and I'm almost positive it was a model 114 power supply. Should be an orange or dark red color about the size of a CD-Rom drive (more or less) and has a flange on one side so you can slide it into the card rack. Also features a standard NEMA computer power socket on the back for connection to 120V AC.

Hope this helps.

The print for this supply is in the CP50 diagram in the manual section of this forum.
The CAT114 pinouts are as follows:
RED +24VDC
BLUE +12 VDC
Green Ground
YELLOW -12 vdc
Not a whole lot to this supply.

To bad you dont have a CAT150F card [Wink]
